We present a new NMR method for measuring ¹H-²H dipolar couplings in macroscopically oriented media. To overcome the lack of dipolar resolution in 1D ¹H and ²H spectra of deuterated molecules, we use a 2D heteronuclear correlation experiment where ¹H chemical shifts and ¹H-²H dipolar interactions in the first dimension are correlated with ¹³C chemical shifts and ²H-¹³C dipolar interactions in the second dimension. The technique is demonstrated on a columnar liquid-crystalline phase.
